Step 3: Cut the Straws
First of all cut the straws according to the dimensions from previous step. Use whatever measurement unit fits to your material. I have used millimeters.
Make the "j" and "k" arms ten units longer and the "a" arm double in size.
For easier work, flatten the tubes.
Using adhesive tape, bind the pieces together. A pair of legs is formed by two modules, in a mirrored position, linked via the "a" arm.
You need at least 3 pairs of legs.
